             Bug #: 55249
           Summary: Multiple copy constructors for template class lead to
                    link errors
    Classification: Unclassified
           Product: gcc
           Version: 4.6.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org

Following code leads to linker errors in C++11 mode and in default mode
(requires replacement of std::array with boost::array):

#include <array>
#include <vector>

template <class TypeT>
struct inner_type {

    inner_type() {}
    inner_type(inner_type& ) {}
    inner_type(const inner_type& ) {}

    ~inner_type() {}
};

// Uncomment typedef to get undefined reference to 
// __uninitialized_copyILb0EE13__uninit_copy
// Can be workaround by marking inner_type copy constructors with noexcept
//typedef std::vector<std::array<inner_type<int>, 3> > type;

// Uncomment typedef to get undefined reference to 
// `inner_type<int>::inner_type(inner_type<int> const&)'
//typedef std::array<inner_type<int>, 3> type;

int main()
{
    type t1;
    type t2 = t1;
    return 0;
}
